PURPOSE: A manufacturing method of a positive electrode active material precursor for lithium secondary battery is provided to reduce the reaction temperature by promoting the generation of positive electrode active material. CONSTITUTION: A manufacturing method of a positive electrode active material precursor for lithium secondary battery consisting of an external bucket and internal bucket, and a vortex reactor in which inflow ports(61a,61b,61c) and outflow ports(62a,62b,62c) are arranged, comprises: a step of mixing by relative rotation movement of the external bucket and the internal bucket by putting metal salt solution, basic solution and ammonia solution into the inflow port; and a step of discharging a positive electrode active material precursor which is a product of the mixing through the outflow ports. |
